My curriculum vitae.

I am a Junior Fellow of the Simons Society of Fellows, working with Ivan Corwin in the Department of Mathematics at Columbia University in the City of New York.

I am co-organizing the Columbia Probability Seminar. My research is supported by the National Science Foundation under Grant No. DMS-1712575.

I received my PhD in Mathematics at Stanford University in 2016, with my PhD advisor Amir Dembo. I was a KITP Graduate Fellow in 2016.

My research interest is in probability theory, in particular the asymptotic fluctuation of interacting particle systems. Before joining Stanford, I worked on the kinetic theory of gas with Tai-Ping Liu.
